The professional competencies of the teacher are of great importance in all educational levels, however in primary school, which is an important part of basic education, the importance of this situation is more prominent. In this sense, the aim of this study is to develop the general proficiency perception scale for teaching profession for elementary school teacher candidates. In this context, data collection tool was offered on a voluntary basis to 547 teacher candidates, face to face or online, and the necessary analyzes for the validity and reliability of the measurement tool with the collected data were made with the SPSS and LISREL programs. In the process of testing the validity of the measuring tool, in order to test the content validity, expert opinions were consulted, and necessary corrections were made. After the adjustments, the comprehensibility of the measuring tool was tested on a small group, and then a pilot application was made. After the obtained data were tested for their suitability for the analyzes, necessary analyzes were made with the obtained data. In the process of testing structural validity, as a result of the exploratory factor analysis, it was seen that the scale consisted of one dimension, and to what extent the theoretical structure was supported with the confirmatory factor analysis. Subsequently, by comparing the scores of the lower and upper quartile groups, internal criterion-based validity was tested, and external criterion-based validity was tested with the Kruskal Wallis H-Test. In the process of testing reliability, Cronbach Alpha Coefficient was used, and item total correlations were examined. As a result of the study, it was seen that the "General Proficiency Perception Scale of Teacher Profession" was a valid and reliable measurement tool that can be used to measure the teacher candidates' perceptions of general competence.
